Unknown driver card

[Ampgutz]

Does anyone recognize this driver card? If so I need to know u170 and u305. Thanks!

MC14060B near the crystal.

LM361.

This diagram has the layout with the driver boards (slight differences). The BP1200 is a slightly better manual.

Viper had a 5ch like this.

The JBL documentation is pretty good to let you know what you're working with.
